Location: Fraser Valley, Lower Mainland, Alouette Lake Project Summary
Sockeye were extirpated from the Alouette system in 1928 by the Alouette Dam. In 2005, an experimental release of hatchery coho salmon took place to evaluate the ability of smolting salmon to migrate out of the reservoir over a surface spillway. In 2005, approximately 10,000 ‘smolt-like’ kokanee migrated out of the reservoir. Experimental releases of surface water continued in 2006 and 2007 with 5,000 and 70,000 ‘sockeye/kokanee’ migrating from the reservoir, respectively. The first adult return of Alouette sockeye occurred in 2007 with 28 adults returning. 36 adult sockeye returned to the Alouette River/Reservoir in 2007 and 53 have returned in 2008. This proposal is to track adult sockeye spawners in 2009 within the Alouette Reservoir to their as yet unknown spawning areas. Returning sockeye will be captured at an adult weir, tagged and released into the reservoir and tracked with acoustic/radio technology. 2009 is the preferred year to conduct the tracking because a large number of adult sockeye are anticipated to return based on an emigration of 70,000 juvenile sockeye from the Alouette Reservoir in the spring of 2007. This project is part of several studies to further the understanding and feasibility of reintroducing sockeye salmon (and other species of salmon) to the Alouette Reservoir, including the upgrading of the Alouette fish weir to support sockeye captures, genetic testing of returning adults, and continuation of monitoring of the outmigration of sockeye each spring.
